SPECIFICATION forming part of Letters'Patent No. 593,865, dated November16,1897. Application iled January 27, 1896. Serial No. 577,041. (Nomodel.)

.To @ZZ whom it may concern:

Be it known that I, BENJAMIN TALBOT, a subject of the Queen of GreatBritain and Ireland, and a resident of Pencoyd, Montgomery county,Pennsylvania, have invented certain Improvements in Gas-Producers, ofwhich the t following is a specification. 1

My invention consists of certain improvements in that classofgas-producers known as Water-seal producers which have the ash-outletat the bottom closed'by a water seal, air under pressure being forcedinto the mass of ashes in the lower portion of the producer and risingtherefrom into the superposed mass of incandescent fuel, the water sealpreventing the escape of air through the ash outlet or outlets, butpermitting the withdrawal of the ashes therefrom without arresting theoperation ofthe producer.

The objects of my invention are to simplify the construction and therebylessen the initial cost of the producer; to permit of the removal ofashes from any point around the producer; to provide for the readychange of the producer from forced tonatural draft, or vice versa; toinsure the ready discharge of the contents of the producer when suchdischarge is required, and to facilitate repairs.

These objects I attain in the manner hereinafter set forth, referencebeing had to the accompanying drawings, in which- Figure lis a verticalsection of the lower portion ofa water-seal gas-producer constructed inaccordance with my invention. Fig. 2 is a sectionalplan view onv theline 2 2, Fig. 1. Fig. 3 is a transverse section, partly in elevation,on the line 3 3, Fig.'2. Fig. 4 is a perspective view of one of thesections of the ashhopper, and Figs. 5, 6, and 7 are enlarged viewsillustrating the details of one of the poke-holes or draft-openingstherein.

' A represents the body of the producer, which consists by preference ofa cylindrical iron or steel shell or casing A with a lining of somesuitable refractory material. The body of the producer is supported atsome distance above the base or foundation B of the structure by meansof a number of legs D, of which four are shown in the present instance,although 5o more or less than this number may be,V employed, if desired,it being advisable, however, to use as few as possible in order thatfree access to all parts of the bottom of the structure will not beobstructed..

The legs D may be made in any appropriate manner,those shown in thedrawings being built up of ordinary structural shapes united to thecasing of the producer-body and to channel-bars D, wl1ich constitute theboundary of the water-seal pit F, the latter being formed, preferably,of concrete or masonry, and being for convenience rectangular in form,as shown in Fig. 2, although this form may, as will be evident, bedeparted from to any extent, as circumstances may suggest, withoutaffecting my invention.

Depending from the bottom of the producerbody A is an ash-hopper exposedexternally to atmospheric pressure only and composed of a series ofsegments G, having at theiredges flanges a., whereby they may be boltedtogether, each of these hopper-segments G having at the top projectingears b, so that when the hopper-sections are fitted together the ears ofadjoining sections will meet and will form openings for the reception ofbolts d, mounted in brackets c?, secured to the casing of theproducer-body, thus providing for the suspension of the ash-hopperbeneath'said body. The brackets d are slotted and the bolts d areprovided at the top with heads d2, having a pi-votal bearing on saidbrackets, so that the depending hopper can have a lslight lateralmovement to provide for shaking down the ashes therein, such movementbeing imparted by any suitable .means-as, for instance, bythe lever cl3and link d4. (Shown in Fig 3.)

Another function of the movable ash-hopper is to cause the breaking upof clinkers and ash-lumps at the line of junction of the hopper with thefixed upper structure of the producer, the movement of the lower masscontained in the ash-hopper in respect to the fixed upper mass containedin the body of the producer causing aA grinding or scraping whichefaction between these two masses fects the desired result.

The depending ash-hopper is of such depth that it will dip into thewater in the pit F to IOO such an extent as to provide a seal of theproper depth, and in two diametrically opposed sections of saidash-hopper above the level of the water seal are formed flanged openingsf for the reception of pipes g, which support a box or casing g',centrally located in the ash-hopper. Rising from this box or easing g isa short vertical pipe g2, having a cap ring or sleeve g3, upon which ismounted a double conical hood g4 g5. One of the pipes g has in thepresent instance a plug at the outer end, but the other communicateswith any available means of supplying air under pressure, the preferredmeans being a steamjet, which induces a iiow of air into and through thepipe. The air rises through the pipe g2 and escapes from beneath thehoods g4 g5 into the mass of ashes inthe lower portion of the producer,through which it rises to the incandescent mass of fuel above the ashes.Air may be forced through both pipes g, if desired, or through either ofthem, as may be found to be most convenient.

rlhe water seal in the pit F prevents the escape of air downward fromthe ash-hopper, but permits of a withdrawal of ashes from beneath thesame, and it will be observed that the said hopper is entirely free atthe bottom, so that ashes can be Withdrawn at any point around thehopper, the slight amount of space occupied by the supporting-legs D ofthe producer-body constituting no practical obstruetion to such removal.It will be observed, moreover, that the ash-hopper is exposed on allsides to a free circulation of air, whereby the thorough cooling of theashes before they reach the water seal is provided for and the formationof water-vapor which occurs when hot ashes are brought into contact withthe water seal is prevented, this being a desirable result, as the riseof steam from the water seal to the incandescent fuel in volume greaterthan can be readily decomposed by the latter is in -practice always tobe avoided.

By making the depending ash-hopper in sections one or more of the lattercan be readily removed when it is desired to dump or discharge thecontents of the producer without removing the entire hopper, andfacilities are always afford-ed for repairing any part of the hopperwhich needs such repairs without disturbing any other portion of thestructure.

In each of the sections of the hopper I form by preference a number ofpoke-holes or draft-openings t', each of which is surrounded by anexternal iiange vl, recessed for the reception of bolts i2, whereby aresecured in place plates t3, which overlap and serve to retain in placebushings m, inserted in the openings t', these bushings being taperedfor the reception of tapered plugs n, so that in the ordinary working ofthe producer the openings are all closed, any one of the plugs, however,being readilywithdrawn when it is poker or other implement for actingupon the ashes or clinkers contained in the ash-hopper, all of the plugsbeing withdrawn when it is desired to operate the producer by naturaldraft instead of by means of a forced blast of air. The bushings can bereadily replaced when worn, thus .increasing the term of service of eachsection of the ash-hopper.

By the use of the exposed water-sealed ashhopper having an internalair-supply the poking of the ashes through the poke-holes of the hoppercan be effected without cutting oif the air-supply, so that the produceris continuous in its action.

It will be evident from the foregoing description of my improvedgas-producer that the same can be constructed without excessive initialcost and can likewise be maintained in operative condition with thegreatest economy, while the practical operative requirements of easyremoval of ashes, proper cooling of the ashes before they reach thewater seal, and ready access to any and all parts of the lower portionof the structure have been properly met.

Having thus described my invention, I claim and desire to secure byLetters Patentl. A water-sealed gas-producer having a body supportedupon legs above a sealing-pit, an ash-hopper suspended from said bodyand depending into said sealing-pit, said hopper being exposed toatmospheric pressure only, and having poke-holes forlned in it, and aninternal air-supply pipe within the hopper, substantially as specified.

2. A gas-producer having a body supported above a sealing-pit, and anash-hopper, exposed externally to atmospheric pressure only, said hopperbeing suspended from said body by means of bolts and depending into saidsealing-pit, substantially as specified.

3. The combination of the elevated body of the producer, the suspendedash-hopper composed of sections secured together and each havingprojecting ears, with suspending bolts mounted in brackets on the bodyof the producer and passing through openings formed in the projectingears of the hopper-sections, substantially as specified.

4C. A gas-producer divided horizontally and having the lower portionwater-sealed and mounted so as to be susceptible of movement in ahorizontal plane each portion containing a mass of fuel whereby thecontents of said lower section are caused to move in contact with thecontents of the upper fixed section at the line of division,substantially as specified.

5. The combination of the elevated body of the producer with thedepending ash-hopper, suspending bolts therefor having heads pivotallymounted on said body, and means for moving the hopper transverselybeneath the producer-body, substantially as specified.
